Abstract
Within human history, individuals and groups who study, or claim to study, the paranormal, have used devices to assist in their communication with those who have passed. Paranormal objects ranging from the Ouija Board to the latest in electronic media and apps are still in use by ghost hunters and self-proclaimed paranormal researchers with mixed reviews.
However, recent developments in the area of ultrasonic sensors have opened a new doorway for an area that has, in many ways, been shrouded in mystery and doubt.
The theory is that it is possible that these ultrasonic sensors can pick up audio outside of the normal range of human hearing. If this suggestion holds merit, then perhaps it is then possible to record voices from spirits or souls on a particular frequency outside the realm of human hearing.
Notwithstanding, testing was performed in Pittsburgh, Pennsylvania under various conditions to discover whether results could be produced.

THEORY
Basing the theory on different principles of laws and thought, ranging from the third law of thermodynamics to the more abstract of consciousness being energy.
The premise that human speech is measured at various frequencies can be of particular interest in that it means human speech is energy that travels. As thermodynamics states, energy cannot be created or destroyed, it simply transforms and goes into entropy. Therefore, this law must also apply to speech.
As an example, according to the American Speech-Hearing Association, a test among 332 male and 202 female subjects aged between 18 – 36 concluded that male voices are generally measured as having a vocal frequency range of 78 and 698 Hz, and women had a range of 138 and 1108 Hz, (Hollien et al., 1971).
Many humans can hear between 20 Hz to 20,000 Hz, but, are most sensitive to 500 Hz and 4,000 Hz, (Williams, 2022) which makes understanding one another accessible to the overall populace. However, anything outside of this range is inaudible to use without the assistance of specialized equipment.
The lion's share of research has found that sound is carried on a wave which, in its simplest form, is a disturbance of energy traveling and pushing the surrounding air (D'Augustino, 2018). If one is to know the frequency range that speech is measured and heard, and that sound is energy carried on a wave, that energy will never die, and that consciousness is energy, perhaps the idea that all elements combined to capture and hear electronic voice phenomena in the ultrasonic field could be plausible.
Testing
The first test was performed on November 6, 2022, at 2230 hours in a standard spare room within a residential home.
Items used for the test are as follows:
1. 100 Watt full Spectrum Lightbulb.
2. Tackstar Shotgun Microphone with a +10 decibel boost.
3. A 16mm ultrasonic receiver connected to an amplifier board, frequency tuner, and 3-inch speaker.
4. 4-Inch PC Fan with attached magnets to the blades.
5. Polaroid Infrared Light.
6. Dell Laptop.
For this experiment, the PC fan with magnets was aimed six inches away from the ultrasonic sensor. Approximately two feet behind the fan is the full spectrum lightbulb, also aiming toward the sensor. The microphone is aimed one-half inch away from the speaker and connects to the laptop via a 3.5 mm audio cable.
Both light and sound travel on different waves, therefor using the full spectrum light and fan with attached magnets would hopefully create fluctuating frequencies the ultrasonic sensor can pick up. The test was to see if moving air that is manipulating a wave, could create an EVP or Electronic Voice Phenomenon.
For the purposes of having checks and balances, the testing is recorded live on YouTube via Stream-Yard. In this fashion, an audience can attend as they please and view the actual usage of the device in real-time. The room in which the test was performed was left unaccompanied with the door and windows closed for a total of 8 hours. (Page, 2022)
With testing the unknown, results can sometimes be utterly shaky. However, the results from the first night were surprisingly promising. The first hour of footage produced vocalizations of both men and women. The voices sounded distant and were under the ambient noise of the room. However, they were indeed there. An example of what was captured with time stamps is as follows:
· Come here (29:49)
· Get it out (34:24)
· Ass for cash (34:37)
· Uh Oh (38:29)
· I like it here (01:03:05)
Additional tests attempted to recreate that first night are performed on various dates under different conditions. Below is the chart with the dates, variables, and results:

Additional Testing
Sensor Limitations A few things to note about the Ultrasonic Receiver in use during these tests: 1. Ultrasonic Receivers CANNOT measure through walls, only air. 2. They DO NOT measure past 70 feet. 3. Due to speed of sound limitations, the fastest rate is 200 Hz at a max distance of about 24 inches. (Senix, n.d., Table Basics) What this information tells us is that the words that were picked up were not from a nearby television or radio due to the fact that the sensor was in a closed room (walls on all sides). Additionally, with the sensor only able to reach no further than 70 feet, its full capacity was cut extremely short in the test due to the room being no larger than 14 feet in length and 13 feet in width. Additional Findings The audio was recorded and reviewed with Adobe Audition software. While reviewing the audio, it was noted that all the perceived voices appeared to rest within the 1k to 2k Hz frequency with a -12 DB boost. Moreover, all the voices that were heard appeared to come through either softly or in a whispering form. Considering audio is energy and travels on a wave, moving the air around said energy, this whisper phenomenon would make sense, as air has no discernible sound associated with it. Additionally, an equalization boost within the 500 Hz to 2000 Hz range was also performed to assist in bringing the speech forward. Nonetheless, it may be plausible that if consciousness is energy, as theorized by Molecular Biologist Johnjoe Mcfadden (McFadden, n.d.), perhaps speech could be linked to that consciousness and be created via air mass as demonstrated by the use of the fan with attached magnets. Conclusion Throughout history, people have sought the assistance of devices to hopefully contact ghosts or spirits. Consequently, when one observes the rules of science, thermodynamics states that energy is not created and does not die. Rather, that energy will change form and travel on into entropy; or the chaos of the universe. Moreover, decades of research reports show that speech is energy that travels upon a wave. If one is to combine that knowledge with the theory by JohnJoe McFadden that consciousness is also energy, perhaps capturing disembodied voices is possible. If a person is to allow their imagination to wander, even the tiniest bit, the energy that is self-aware may be able to utilize air patterns to form speech. Accordingly, this speech could disrupt air patterns when it travels, perhaps it is plausible that speech in the form of conscious energy can be recorded within the ultrasonic spectrum
